[High-risk breast lesions].

Breast lesions with malignant potential are the morphological expression of tissular troubles, foregoing the in situ cancer and then invasive. Breast dysplasia, like fibro-cystic mastosis with typical epithelial ducto-lobular proliferation can progress in a relatively long time interval towards in situ carcinoma. Classical advising, that any breast masses should be regarded as a potential cancer, until it's nature is not pathologically characterized, still remains actual. The clinical and imaging diagnosis for mastopathy at risk and the approaches for a therapeutic manner represent today a real possibility for early treatment.
